DOUBLE-CYLINDER OIL-MOTOR.

SPECIFICATION forming part of Letters Patent No. 669,514, dated March 12, 1901.

Application filed March 12, 1900. Serial No. 8,332. (No model.)

To all whom it may concern:

Be it known that I, JAMES W. EATON, a citizen of the United States of America, and a resident of West Islip, county of Suffolk, Long Island, New York, have invented Improvements in Double-Cylinder Oil-Motors,of which the following is a specification.

My invention relates more particularly to that classof oil-motors in which impulses are imparted to the pistons in the cylinders by intermittent explosions of air charges and sprayed or vaporized oil in the vaporizingbu1bs,which are in direct communication with the cylinders. In twin-cylinder or two-cylinder motors of this character as now constructed each cylinder has its own separate ignition or vaporizing bulb, and it is found a vertical section on the line 1 1, Figs. 2 and 3, of my duplex ignition-bulb and the upper part of one of the cylinders of a twin-cylinder oil-motor. Fig. 2 is a vertical section on the line 2 2, Figs. 1 and 3, and Fig. 3 is a sectional plan view on the line 3 3, Figs. 1 and 2.

A and A are the two cylinders in which work the single-acting pistons of a tWin-cyl I inder oil-motor, and a, a are water-jackets around these cylinders. Mounted upon the cylinders are the vaporizing orignition chambers, into which jets or sprays of oil are admitted intermittently and which communicate with the motor-cylinders for the admission of air charges from the latter and for the return to the cylinders of the expansive gases due to the ignition of the combustible mixture of air and vaporized oil. Means are provided for the preliminary external heating of the vaporizing-chambers; but in the operation of the engine after the required degree of heat of the chambers has been attained the periodicalinternal ignition and explosion of the combustible mixture will keep up the necessary degree of heat of the chambers.

As seen in the drawings, the ignition-chambers I3 B are in one duplex bulb, which may conveniently be made of a spherical shape as to its main body; but the important feature is that the two chambers B and B, which communicate through ports or passages b and b with their respective cylinders A and A, have bet-ween them a wall 13 common to both. Each vaporizing-chamber B B has its own valved spraying-nozzle O O for the intermittent admission of a jet or spray of oil, these nozzles preferably being set as shown in Fig. 1. Around the part of the casing through which theoil-nozzles are projected I prefer to provide water-jackets d in communication with the water-jackets a of the cylinders, 00 being the point of outlet for the water.

Any suitable means for externally heating the ignition-bulb to start the engine may be provided. In Fig. 1 I have indicated a vaporburner E to throw a jet of flame for a few minutes against the exterior of the bulb to bring it to a suitable heat before the first admissions of oil-sprays and air charges. As soon as the engine has been fairly started this burner may be withdrawn or its flame extinguished,and thereafter the continued operation of the engine will keep the ignitionbulb suificiently heated owing to the intermittent ignitions of the combustible mixture of air and vaporized oil.

With the described construction of duplex ignition-bulb it will be an easy matter to restart either part of the motor after it has been thrown out of action or stopped for a time, because the division-wall B common to the two ignition-chambers B B, will be kept hot by the intermittent ignitions continuing in that chamber which is kept in operation, and this hot wall will suffice to ignite without the use of external reheating means the newly-admitted supplies of air and oilspray to that chamber B or B which had been temporarily out of use.

While in this specification I speak. of the use of oil, it will be understood that I use the term oil-mot0rin a su fficiently general sense to include the use of like liquid fuels, such as alcohol, for instance.

I claim as my invention- 1. The combination of the two working cylinders of an oil-motor, with a duplex ignitionbulb, having its two chambers each in communication with a cylinder and a dividing- Wall common to said two chambers, substantially as described.

2. The combination of the two working cylinders of an oil-motor with a duplex ignitionbulb having its two chambers each in conimunication with a' cylinder, and a dividingwall common to said two chambers, with oilnozzles opening into the two chambers and means for externally heating the duplex bulb; In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
